Ignoring air resistance, the distance, d (in meters), that an object drops in t seconds is given by the equation d=4.9t^2

Find the distance traveled in 5 sec.
Sub 5 for t
=====================
Find the time required for the object to fall 50 m. Round to the nearest tenth of a second.
4.9t^2 = 50
Solve for t
==================
Find the time required for an object to fall from the top of the Canada Trust Tower in Toronto, Canada, if the building is 261 m high. Round to the nearest tenth of a second.
4.9t^2 = 261
Solve for t
